QuantumScape Corporation is trading 5% down at $7.28, extending a sharp slide triggered by recent disclosures of insider selling.
- The stock previously fell over 16% on June 5, 2026, after filings showed CTO Timothy Holme and other insiders converted and sold Class B shares into Class A shares under Rule 10b5-1 plans.
- The insider activity continues to act as a significant overhang on the share price, reflecting fragile investor sentiment toward the pre-commercial battery developer.
